ABSTRACT

The unsteady flow and heat transfer flow of a viscous fluid in the stagnation region of a three-dimensional body embedded in the fluid-saturated porous medium was studied. The effects of the presence of the solid matrix and of viscous dissipation were analyzed. Both the nodal-point region and the saddle-point region were considered. With appropriate transformation, the boundary layer equations were reduced to semisimilar equations. Numerical solutions of these equations were obtained using the local nonsimilarity method with second-order truncation.
